1931. Serial No. 552,136.

This invention relates to improvements in apparatus for makingtapestried brick and the like, and is a divisionof my pendingapplication, Serial No. 422,586, filed January 22 1930.

My invention contemplates an apparatus embodying means for forming andmoving a continuous column of clay or other suitable material of thedesired dimensions, and scoring means for forming a series of curvedgrooves or gutters on the surface of the column and on one or more facesof the resulting bricks, said means including an angularly rotatablehead having an annular series of scoring pins thereon for engaging themoving column, and actuating mechanism therefor.

In the drawings, showing the invention somewhat diagrammatically:

Fig. 1 is a perspective view of the apparatus embodying my invention;

Fig. 2 is a similar view of one of the resulting bricks after severancefrom the column Fig. 3 is a view of the apparatus partly in sideelevation and partly in section;

Fig. 4 is a plan view of Fig. 3;

Fig. 5 is an end view of asevered brick; and

Fig. 6 is a plan view of such brick.

Referring to the drawings, A designates a portion of a brick machineadapted to contain a plastic clay mixture, and having a reciprocableplunger B therein for compressing and delivering the clay outwardly froma discharge nozzle 3, to form a continuous column or bar 2 of a desiredshape and size.

Various other well known means may be employed for extruding the plasticclay into a column or bar.

For the purpose of imparting a series of curving part circular scoremarks 4: of ragged outline and gutter or groove form, I provide a diskor head 5 suitably mounted on and rotatable by a driving shaft 7 abovethe top surface of the column or bar 2. The axis of said shaft and diskis inclined to the surface of the column 2, as particularly shown in Fig3.

The lower side of the disk 5 is provided with an annular series ofspikes or pins 6 spaced radially in a plurality of series from the.outer edge of the disk inwardly, as shown.

As the column or bar 2 ismovedjoutwardfrom the nozzle or dle 3, thed1sk5 1s rotated by its shaft 7, pins 6 sweeping around, over andthroughtheupper surface of the clay column,

forming a continuous series of ragged, rough edge, irregular butregularly spaced curved lines or score marks 4.

One'or both edges of the column or bar 2 may be treated in the samemanner by means of a similar disk 5a rotatable by a shaft 7a, and havingsimilar pins 6a thereon. Said disk and shaft are similarly tilted orinclined to the surface of the bar, so that the pins engage only at theside where the disk is closest to the bar. 'By such arrangement the pinsbeyond the center of either disk are elevated beyond the surface of thebar and do not out into it, except at the other or lowered side of thedisk. l

The effect of such treatment is to impart a continuous series of suchcurved score marks across the face or faces of the bar, increasing a indepth towards the middle thereof and decreasing in depth from the middletowards the other edge.

When it is cut or severed into the brick units, as by wire cutting, eachsevered brick is covered on its edge or end or ends with such plowedmarks 4, as shown in Fig. 2. When the bricks are burned in the usualway, the curved score marks give to the faces of the brick an attractiveor ornamental appearance, greatly enhancing its value in an artistic andnovel manner.

It will be understood that the rotatable disks may be mounted by theirdrive shafts or other means so as to be adjusted towards or from thesurface of the bar or with variation of inclination, and otherwiseprovided with suitable driving gearing and other necessary mechanism, inorder to effect the operation to the best advantage.

The speed of operation, spacing of the pins, number of annular rows, andother details of operative mechanism may be entirely within the controlof the machine builder.

What I claim isi 1. In brick making apparatus, the combination withmeans for forming a continuous moving bar of plastic clay, of arotatable head located at an angle to the surface of the bar having anannular series of scoring pins.

2. In brick making apparatus, the combination with means for forming acontinuous moving bar of plastic clay, of a rotatable series of scoringpins operable in an annular path in sloping relation to theface of thebar and traversing its surface at varying depth.

3. In nation with a machine for forming a continuous bar of plasticclay, of a rotatable series of scoring pins operable in an annular pathwithin the width of the face of the bar being operated on and in a pathnon-parallel to the face of the bar.

- 4. In brick making apparatus, the combination with means for forming acontinuous moving bar of plastic clay, of a rotatable series of scoringpins operable in an annular I path in sloping relation to the face ofthe bar adapted to engage the edge portion of the face at a minimumdepth increasing towards its middle and decreasing in depth towards itsopposite edge portion.

5. In brick making apparatus, the combination with means for'forming acontinuous moving bar of plastic clay, of a rotatable head located at anangle to the surface of the bar having an annularly movable scoring pm.

In testimony whereof I hereunto aflix my signature.
